Free Sales Tax Calculator

Calculate sales tax and total price, or work backward from a total.

Sales tax rates vary by state, county, and sometimes city — this calculator doesn't look up rates automatically, so enter your local combined rate. Switch to "Total → Price" mode when you have a receipt total and need to back out how much was tax.
